FAQs
What is FAN7313?
The FAN7313 is a high-performance, current mode PWM controller designed by Fairchild Semiconductor. It is often used in power supply and lighting applications, providing reliable and efficient control of switch-mode power circuits.
How Does FAN7313 Work?
The FAN7313 operates by regulating the switching of power transistors in a power supply or lighting circuit to achieve a stable output voltage or current. It utilizes a current mode control scheme to provide inherent overcurrent protection and ease of loop compensation. The controller features adjustable switching frequency and soft-start functions for enhanced flexibility and control.
How Many Pins does FAN7313 have and What are the Functions of the Pinout Configuration?
The FAN7313 is housed in an 8-pin SOP (Small Outline Package) package. The pinout configuration includes:
- VCC: Power supply pin.
- COMP: Compensation pin for loop stability.
- FB: Feedback pin for output voltage regulation.
- SENSE: Current sense input for overcurrent protection.
- GND: Ground pin.
- RT/CLK: External resistor or clock input for setting frequency.
- SD: Shutdown pin for enabling/disabling the controller.
- CS: Current sense input for overcurrent protection.
What are the Pros and Cons of FAN7313?
Pros:
- Current Mode Control: Offers inherent overcurrent protection and ease of loop compensation.
- Adjustable Frequency: Provides flexibility with adjustable switching frequency.
- Efficiency: Enables efficient control of switch-mode power supplies for power savings.
- Compact Package: The 8-pin SOP package is space-efficient and suitable for compact designs.
Cons:
- External Components: May require additional external components for optimal performance in certain applications.
- Complexity: Current mode control schemes may require careful understanding and design considerations for high-performance applications.
Are There Any Equivalents/Alternatives to FAN7313 for Recommendation?
Alternatives to the FAN7313 include the UC3843 from Texas Instruments and the NCP1200 from ON Semiconductor.
